From the 29th Bulletin of the Grande Armee 1812
Our cavalry was dismounted to such a degree, that it was necessary to collect the officers who had still a horse remaining, in order to form four companies of 150 men each. The Generals there performed the functions of captains, and the colonels of subalterns. This sacred squadron, commanded by General Grouchy, and under the orders of the King of Naples, did not lose sight of the Emperor in all these movementsI painted up the Sacred Squadron back in March, here, but I wanted the chap giving General Grouchy his orders, so the search was on for a suitable Marshal Murat, the King of Naples.
There are plenty of pictures on the internet showing Murat in a multitude of different coloured and flamboyant uniforms, such as the pic above, which I based my figure on.
The figure comes from the excellent range of French Napoleonic Commanders from Gringo 40's, the figure represents Murat in 1807 during the Battle of Eylau, click here.
As Eylau was fought in the winter, it seemed the best fit, and I'm sure you'll agree kinda matches the reference picture above. Now as their name suggests Gringo 40's, they are a tad on the large side, but as he's all on his own when based up, I don't think it makes a lot of difference.
He can of course be used as a General figure anytime during a game, not just for the Sacred Squadron.
